The Tektronix VM700T Video Measurement Set delivers integrated waveform monitoring, vectorscope analysis, picture display, and automated measurement capabilities for broadcast, post-production, and manufacturing environments. This dual-channel instrument processes serial digital video at 143 Mbit, 270 Mbit, and 360 Mbit rates per SMPTE 259, along with analog composite video and AES3 digital audio. Built for baseband video and audio signal verification, it supports unattended monitoring, user-programmable functions, and remote operation.
